Vehicle goes into reduced power modes at any highway speeds. The codes involve a throttle body, crankshaft sensor and pedal. This is extremely damgerous at highway speeds since vehicle is immobile.

problem #1

P2135 throttle/pedal position sensor/switch A/B voltage correlation that puts the vehicle into "stabilitrak disabled", "traction control disabled", and "reduced engine power". while there is a tsb#11-06-04-007B regarding this issue and warranty coverage; unfortunately it does not apply to my engine. However, since this is a widely know issue, and this vehicle is experiencing the same conditions, one would think that my vehicle would be serviced under this tsb extended warranty coverage. 12/04/2014: First service attempt: Clear code everything tests fine, let"S see if it happens again. 12/10/2014: Second service attempt: Both throttle body and acc pedal position sensor tested "good". weak battery - replace battery. 12/22/2014: Third service attempt: Tech replaced accelerator pedal. Relearned throttle/idle. 12/26/2014: Forth service attempt: Relearned throttle/idle procedure. 01/13/2015: Fifth service attempt: Reprogram and apply 6 updates to ECM. 01/14/2015: Code thrown again: Dealership advising to replace throttle body (but uncertain that this will fix the problem)?
